Hi Jan, Yes the lower ones have the molding compound splashed over the tab. The upper ones are totally clean.
Also the lower ones have small indents that the upper ones do not have.
The lower ones do work in my amp but I will try the upper row also and listen to the difference.

Originally posted by ACD I also notised those small dots from the mold

It could be interesting if you can hear any difference, however telling the difference may be impossible

Interesting in this connection is you specified MJE15032 and MJE15033 for the VAS in Krell clone. I would rather use something like the displayed Toshibas. Any reason for your choice?
If I don't hear any difference there is no point to bother.

Jan,
You switched the u and the o in the last quote. Not really inportant to me.
I can try the MJE parts too as I have plenty of these.
Why bother with blind listening tests? I am am the only one listening to my amp. This machine is for listening pleasure so if I like it is is good to me regardless what visitors tell me or double blind listening tests reveal.
